A flexible transmission device utilizes two flexible cables or ropes to pass through a narrow passage and connect two operating elements. An extendable mechanism is an intermediate of the two flexible elements. The extendable mechanism includes two tubes co-axially linked to each other. The two flexible elements overlap in the extendable mechanism in a free moving condition, which allows the relative distance between the two operating elements changing. When a flexible element is pulled from an operating member, a slider connected between the two flexible elements will be biased to fasten the two flexible elements so that the drag force can be transmitted to the second operating member.

1. A flexible transmission device, capable of being applied in a narrow passage to transmit a drag force from a first operating member to a second operating member, comprising:an extendable mechanism, capable of changing axial length thereof, having two ends connecting to said first operating member and said second operating member respectively; a second flexible element, having one end axially connected to said extendable mechanism and moved along therewith, and another end connected to and pulled by said second operating member so as to be straightened; a slider, formed with a through hole to sleeve said second flexible element so as to be freely movable thereon when being supported in a free position, and capable of catching said second flexible element to pull the same when being biased to a grasping position; a first flexible element, mounted axially to said extendable mechanism, having one end fixed to said first operating member, and another end connected to said slider at an axis different from said through hole so as to bias the slider when being pulled; and a retaining element, sleeved on one end of said second flexible element, having one end connected to a portion of said extendable mechanism that is relatively fixed to said first operating member, and another end to pressively support said slider in said free position.
